ELECTRICAL JACQUARD MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 727,023, dated May5,1903.

Application filed $eptember 24, 1900. Serial No. 30,990- (No model.)

To all whom/it may concern:

Be it known that 1, JAN SZOZEPANIK, a subject of the Emperor ofAustria-Hungary, residing at Vienna, in the Province of Lower Austria,in the Empire of Austria-Hungary,

have invented certain new and useful Improvements in Electrical Jacquard Mechanism for Looms and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates to an improved arrangement of the electromagnetsin electrical jacquards which enables the magnet to be easily changedwithout considering the con nections, and consequently enables theconnections of the electromagnet 'to be easily altered. Theelectromagnets are arranged in' such a way that in consequence of theformation of a ring of lines of force one armature cannot influence theadjacent armatures.

Figure l of the accompanying drawings shows, by way of example, thecomplete ar-' rangement of the electromagnets in an electrical jacquardthe electromagnets of which 0 control the movement of the needle asdetermined by an electrical templet. Fig. 2 is a horizontal section ofthe magnet-box. Fig. 3 shows one of the electromagnets in longitudinalsection.

The electromagnets Ct,Wl1lCh act in the usual manner on the armatures d,that control the needle b of the jacquard c, and release them wheninfluenced by the magnets-,are arranged in holes in anelectrically-conducting magnet- 40 boxf and bear with their outer endson contact-buttons g, which are pressed by springs h against the ends ofthe electromagnets. The pins 2', carrying these buttons 9, pass througha contact-boardj and are connected,

5 by means of clamped conducting-wires lc,with pins m, arranged in asecond contact-board l and provided in a similar manner with springcontact-buttons a. Each of the contact-buttons n is spring-pressedagainst a projection 0 of its respective stationary conductingbell-crank lever 0 of the selecting device 19, the movable members 00fwhich. rest on the movable templet q. There is one finger 0 connected toits corresponding be1lcrank lever 0, each of the latter having a singleprojection 0 contacting with its respective button 17.. The fingers 0are thin conductor-plates having at their hinge end a circular cut-awayportion that is more than a half-circle. This recess fits over the boss20 of the upturned lower ends of the conducting-levers 0. These upturnedends are circular, from which segments have been cut on each side of thecenter to form parallel chords. When the free ends of the fingers 0 arelifted to a sufficient extent, they can be slid into position on thecircular portions 20 and as sume the position indicated in Fig. 1, theirends resting on the templets g. This templet comprises, as usual, ametal plate which con- 7o ducts-at portions left bare, but does notconduct at other places which are covered with an insulating material.Underneath the templet there is arranged the current-supplying lever r,which is in contact with it and is connected to the current-supply wire.9, while the return-wire t is connected with a terminal It on themagnet-box.

When a contact-lever 0 touches a bare or conducting place on thetemplet, the circuit is closed and the current flows from 3 through 1"to the templet q,through the corresponding contact-lever 0 and thecorresponding contact-button n and wire it to the second correspondingcontact button g, and then through the corresponding electromagnet a tothe magnet-box f, thence to the terminal at, and back to t. Theelectromagnets are thus selectively energized. The grid d, that movesthe armatures d, one in each opening 61 for each magnet 00, isvertically movable between the needle-board b and the magnetbox, so thatsaid armatures will be moved into alinement with their respectivemagnets.

When so moved, the energized magnets (all 5 of those shown in Fig. l aresupposed to be energized) will attract the armatures and hold them. Thegrid d is then moved down or dropped into the position shown in Fig. 1,

the openings in the grid being larger than too the magnets, so that eacharmature that has been alined with its respective energized magnet willbe held thereby to cover the opening in the needle-board b and preventthe needle from being moved in, thereby holding the respective hooks outof engagement with their griifs. The needles I) are normally heldretracted, and after the armat'u res have been selectively held in placethose so held act as distance-pieces, so that when the needles I) aremoved toward the magnets a those needles opposite the spaces notoccupied or filled by armatures will enter them.

By means of the arrangement described the connections of theelectromagnets can be easily altered, since the contact-boards can beremoved and others substituted therefor. Furthermore, a machine with ,alarge number of lifting-wires can work a machine with a small number, ifall of the electromagnets operating the superfluous needles are cut outby removing their contacts.

In order to permit of the described course of the current and to preventan excited magnet from influencing the adjacent magnets, the magnets aremade as tubulated magnets of special construction. Fig. 3 shows such atubulated magnet on a larger scale.

The conducting magnet-core 1 is surrounded by the winding 2 and isinclosed in a conducting tubular casing 3, which is firmly connected tothe core by means of a screw 4:.

The annular space for the winding 2 between the core and the casing isclosed at one end by the enlarged end of the core and at the other by aring 5. I

To the enlarged end of the core there is secured, by means of a screw 7,that passes through an insulating-sleeve 6, a hoilowedoutcontact-button8, which is completely insulated from the core by means of a disk 9,made of non-conducting material. Between the contact-button 8 and theinsulating-disk 9 one end of the winding is clamped, while the other endof the winding is soldered or otherwise connected to the core at 10. Thecurrent fiows,therefore, from the spring contact-button g of the boardjto the contactbutton 8 of the electromagnet, thence to the core throughthe winding 2, that surrounds it and excites it, and from the corethrough the casing 3 to the magnet-box f, in order to return in themanner hereinbefore described from the magnet-box to the return-wire t.
